Yeah, I'd recommend trying to find a salvage yard one. Sometimes having a They-Pull such as LKQ can hopefully ensure the compressor came from a car that was holding pressure. Lots of After-Cheezy parts that you'll just be replacing the compressor again, or finding a faulty compressor. Like Kodachrome Wolf stated, they're sometimes cheap for a reason... Unless you get lucky and someone has stock of genuine Motorcraft and just want them gone lol.
